Rose plant named ‘Evera211’

ABSTRACT

A new and distinct cultivar of Rose plant named ‘Evera211’, characterized by its upright and mounding plant habit; dark green-colored leaflets; large double yellow-colored flowers; flowers held upright on strong and erect peduncles; and good postproduction longevity.

Botanical designation: Rosa hybrida.

Cultivar denomination: ‘EVERA211’.

BACKGROUND OF THE INVENTION

The present Invention relates to a new and distinct cultivar of Rose plant, botanically known as Rosa hybrida, commercially used as a potted Rose, and hereinafter referred to by the name ‘Evera211’.

The new Rose plant is a product of a planned breeding program conducted by the Inventor in Fåborg, Denmark. The objective of the breeding program was to develop new uniform potted Rose varieties with novel and attractive flower colors, disease resistance and excellent postproduction longevity.

The new Rose plant originated from a cross-pollination made by the Inventor in November, 2005 of two unnamed proprietary Rose selections, not patented. The new Rose plant was discovered and selected by the Inventor in February, 2007 as a single flowering plant within the progeny of the stated cross-pollination in a controlled greenhouse environment in Fåborg, Denmark.

Asexual reproduction of the new Rose plant by cuttings in a controlled greenhouse environment at Fåborg, Denmark since December, 2008, has shown that the unique features of this new Rose plant are stable and reproduced true to type in successive generations of asexual reproduction.

SUMMARY OF THE INVENTION

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Evera211’. These characteristics in combination distinguish ‘Evera211’ as a new and distinct cultivar of Rose:

-   -   1. Upright and mounding plant habit.     -   2. Dark green-colored leaflets.     -   3. Large double yellow-colored flowers.     -   4. Flowers held upright on strong and erect peduncles.     -   5. Good postproduction longevity.

Plants of the new Rose differ from plants of the parent selections in growth habit as plants of the new Rose are more uniform than plants of the parent selections.

Plants of the new Rose can be compared to plants of the Rose ‘Evera 106’, disclosed in U.S. Plant Pat. No. 16,760. In side-by-side comparisons conducted in Fåborg, Denmark, plants of the new Rose differed from plants of ‘Evera 106’ in the following characteristics:

-   -   1. Plants of the new Rose had larger flowers than plants of         ‘Evera 106’.     -   2. Flowers of plants of the new Rose had more petals than         flowers of plants of ‘Evera 106’.     -   3. Plants of the new Rose had brighter yellow-colored flowers         than plants of ‘Evera 106’.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying colored photographs illustrate the overall appearance of the new Rose plant, showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photographs may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Rose plant.

The photograph on the first sheet comprises a side perspective view of a typical plant of ‘Evera211’ grown in a container.

The photograph on the second sheet is a close-up view of a typical flower of ‘Evera211’.

The photograph on the third sheet is a close-up view of the upper surface of a typical leaf, the lower surface of a typical leaf and a typical flower bud (bottom to top).

DETAILED BOTANICAL DESCRIPTION

Plants of the new Rose have not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature and light intensity, without, however, any variance in genotype. The aforementioned photographs, following observations and measurements describe plants grown during the spring in Sabro, Denmark, in a glass-covered greenhouse and under commercial potted Rose production practices. Plants were grown in 10-cm containers, pinched two times and were nine to twelve weeks old when the photographs and description were taken. During the production of the plants, day temperatures averaged 21° C., night temperatures averaged 19° C. and light levels ranged from 8,000 to 10,000 lux. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2007 Edition, except where general terms of ordinary dictionary significance are used.
